Unoziva here mapango matatu eMOSFET?

MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) ine mapango matatu anoti:

Gedhi:G, gedhi reMOSFET rakaenzana nehwaro hwebipolar transistor uye rinoshandiswa kudzora mafambisirwo uye kucheka kweMOSFET. MuMOSFETs, gedhi voltage (Vgs) rinotarisa kana chiteshi chekufambisa chinoumbwa pakati pechitubu uye dhizaini, pamwe nehupamhi uye conductivity yemugero wekufambisa. Gedhi rakagadzirwa nezvinhu zvakaita sesimbi, polysilicon, nezvimwewo, uye rakakomberedzwa neyakaiswa insulating layer (kazhinji silicon dioxide) kudzivirira ikozvino kuyerera yakananga mukati kana kunze kwegedhi.

Kwakabva:S, kunobva MOSFET kwakaenzana neemitter ye bipolar transistor uye ndiko kuyerera kwazvino. MuN-channel MOSFETs, sosi inowanzobatanidzwa kune yakaipa terminal (kana pasi) yemagetsi, nepo muP-channel MOSFETs, sosi yakabatana kune yakanaka terminal yemagetsi. Kunobva chimwe chezvikamu zvakakosha zvinoumba gwara rekuitisa, rinotumira maerekitironi (N-channel) kana maburi (P-channel) kumugero kana gedhi regedhi rakwira zvakakwana.

Drain:D, kudonhedza kweMOSFET kwakafanana nemuunganidzi webipolar transistor uye ndiko kunopinda ikozvino. Kudonhedza kunowanzobatanidzwa kune mutoro uye kunoshanda sechipo chezvino kubuda munharaunda. MuMOSFET, dhizaini ndiyo imwe magumo eiyo conductive chiteshi, uye kana gedhi regedhi richidzora kuumbwa kwegedhi rekufambisa pakati pechitubu nekudonhedza, ikozvino inogona kuyerera ichibva kutsime kuburikidza neiyo conductive chiteshi ichienda kudhiraini.

Muchidimbu, gedhi reMOSFET rinoshandiswa kudzora nekudzima, kunobva ndiko kwainoyerera ikozvino, uye dhiraini ndiko kunopinda ikozvino. Pamwe chete, mapango matatu aya anotarisisa mamiriro ekushanda uye kushanda kweMOSFET. .
